We will be traveling from the extreme SE corner of Michigan to the Niagara Falls/Buffalo area next April. There are two ways that we could go, and I am looking for advice and information. The obvious way is to take I-75 down to the Ohio turnpike and follow I-90 all the way from Toledo to Buffalo. According to Mapquest this way is 329 miles, much of it unimpeded toll road, but also quite boring. The other way we could go would be to take I-75 up to Detroit, cross through the tunnel into Windsor, Ontario and take Hwy 401 up to the Canadian side of the Falls. My road atlas says that this way is 308 miles. Mileage-wise, there isn't much of a difference, but I am wondering if going up through Canada, while it would be much more interesting for our kids since we haven't been through customs in years and neither of them remember it, not to mention the bilingual road signs (our daughter is learning French right now), would take a lot longer. As I mentioned, we haven't been through customs in over ten years, so I don't know if that would waste a lot of time (especially now that it's post-9/11) or what condition Hwy 401 is in; if it's a superhighway or simply a two-lane road. We plan on leaving quite early in the morning, at least by 5:00 AM, so that we can visit the Buffalo Zoo by late morning. If anyone could help me out with some info or advice I would greatly appreciate it. Thanks!
